本文整理了Java中proguard.io.ZipOutput类的一些代码示例，展示了ZipOutput类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZipOutput类的具体详情如下：
包路径：proguard.io.ZipOutput
类名称：ZipOutput

ZipOutput介绍

[英]This class writes zip data to a given output stream. It returns a new output stream for each zip entry that is opened. An entry can be compressed or uncompressed. Uncompressed entries can be aligned to a multiple of a given number of bytes. Multiple entries and output streams can be open at the same time. The entries are added to the central directory in the order in which they are opened, but the corresponding data are only written when their output streams are closed. The code automatically computes the CRC and lengths of the data, for compressed and uncompressed data.
[中]此类将zip数据写入给定的输出流。它为每个打开的zip条目返回一个新的输出流。条目可以被压缩或解压缩。未压缩的条目可以与给定字节数的倍数对齐。可以同时打开多个条目和输出流。条目按打开顺序添加到中心目录，但只有在其输出流关闭时，才会写入相应的数据。该代码自动计算压缩和未压缩数据的CRC和数据长度。
